An unbalanced design. The data originally appeared in Bailey (1953), and was reproduced in Scheffe (1959) with the description:
“...gives the weight of hybrid female rats in a foster-nursing experiment with four types of rats. (The weights are litter averges in grams at 28 days. The within litter variance was obviously negligible compared to the between-litter variance.) The factors in the two-way laout are the genotype of the foster mother and that of the litter. ”
